IMPROVEMENT IN BAILS FOR KETTLES, BOILERS, &c.

Specification forming part of Letters Patent No. 123,648, dated February13, 1872.

Specification describing a new and useful Improvement in Bail forKettles, Boilers, &c., invented by WILLIAM M. STRATTON, of West Troy, inthe county of Albany and State of New York.

Figure 1 is a side view of a stove-boiler illus- I trating my invention.Fig. 2 is a side view of the same, partly in section, through the linea: 00, Fig. 1.

My invention has for its object to improve the construction of boilers,kettles, &c., so as to place them more fully under the control of theperson handling them enablinghim to handle them with ease and safety;and it consists in the bail so constructed as to become rigidlyconnected with the body of the kettle or boiler, whenthe weight of saidvessel is upon said bail, and to become like an ordinary bail when theweight is taken ofi said bail, as hereinafter more fully described.

A represents the body of a kettle, boiler, or other vessel, and B is thebail. In the ends of the .bail B are formed slots b extendinglongitudinally with said bail, to receive the lugs a formed upon thesides of the body A.

a? is a curved flange, formed with a notch or slot formed in its upperor middle part, and with shoulders or stops at its ends. Upon the bail Bis formed a shoulder or stud, 11 in such a position that when the stud ais in the upper part of the slot b the shoulder or stud b may movefreely along the flange 00', allowing the bail to work upon its pivot inthe same manner as an ordinary bail.

When the weight of the vessel A comes upon the bail B, the shoulder orstud b enters the notch or slot in the flange a so as to hold the bail'Brigidly connected with the body, A so long as the weight of said vesselis borne by said bail. This gives the operator full control over thevessel while handling it. As soon as the vessel is set down the bail Bunlocks itself automatically by its own. weight, and drops down upon theedge of the vessel in the manner of an ordinary bail.

The form and arrangement of the parts a 00 b b may be varied, asdesired, so long as the two main features of my invention areretainedviz., the automatic rigid locking of the bail when the weight ofthe vessel comes upon it, and theautomatic unlocking of the said bailwhen the weight of the vessel no longer bears upon it.

Having thus described my invention, claim as new, and desire to secureby Letters Patent- The bail B, having end slots 12 and shoulders bcombined as described with kettlebody A, having lugs a and notched,shouldered, and curved flanges a, as and for the purpose set forth.

WILLIAM M. STRATTON.
